The solar PV modules are generally employed in dusty environments which is the case in tropical countries like India. The power output reduces as much as by 50% if the module is not cleaned regularly. In order to maintain the efficiency of electrical power generated by solar panel we need to clean solar panel regularly that require human effort during cleaning. That increases labour force and thus uncertainties of cleaning increases. Thus we require developing a means of cleaning solar panel autonomously in order to maximize the efficiency and energy output from these panels.

The system consists of water pump and a device. There is water spraying section on the top of every panel that will spray high pressure water on the panel in order to clean it. The device controls direction of flow and the pressure of water. The device has a microcontroller unit which is programmed such that, the whole water pressure, created by pump, is applied to each and every water spraying section individually. So high pressure water is sprayed to every single panel one by one in order to clean every panels in solar power plant. The device also consist a timer which enables supply daily to this system.

• Maximum cleaning with minimum use of water.
• Less space and with low power consumption.
• Daily cleaning improves production of the solar PV plants, by removing the dust from panels
• The most cost effective way of having clean solar PV plants comparing against manual cleaning.
• Is simple, strong, reliable, using high quality components and equipments.
• Depending on the particular PV plants, it is easily customizable to work with no changes to the supporting structure of the solar PV panels and the panels themselves.
• Possibility of programming the operating parameters such as start time and multiple cleaning times.
• Does not use chemical cleaning agents or other products that might harm the environment and solar panels.
• Does not require human intervention during cleaning, removing all uncertainties related to labour force.
• Water pressure created by pump, is applied to each and every spraying section individually. So every panel will clean effectively as water pressure is not divide by every panel.

• Automatic timer operated cleaning system.
• It uses 2.5 litre of water for cleaning single module.
• Power consumption is only 1.5rs a day for cleaning 10 modules.
• It takes 10 seconds to clean one module.
• Water Pump requirements 1 H.P
• Early morning operation can be done so that before sun rises, Panel can be cleaned.
• Operational at high temperatures.
• Device is water resistant.
